Abstract
After the national"carbon peak,carbon neutral"goal was proposed,as a key way to decar-bonize the energy system and achieve zero emissions,the position of offshore wind power is becoming in-creasingly important.Flexible HVDC has the advantages of no charge power problem for long distance transmission,flexible power control and dynamic reactive power support.DC gapless metal oxide GIS tank arrester(referred to as DC GIS arrester)has excellent nonlinear characteristics,under the action of normal operating voltage,its resistance value is high and the leakage current passing through is very small.However,under overvoltage,the resistance value becomes sharply smaller,which is an important protection equipment to protect GIS from overvoltage damage.It plays an important role in reducing the insulation level of quick-closing equipment and improving the safety and stability of power system.In order to meet the needs of offshore wind power projects of±200 kV and±320 kV,the design of±200 kV and±320 kV GIS arrester was studied,the configuration of the arrester resistor,the electric field strength of the internal shield and the pressure of the shell were studied,and the prototype was success-fully manufactured.Through the verification test,the performance of the developed DC GIS arrester meets the engineering needs,and the prototype is suitable for engineering use.关键词
